</p>If you are are experiencing the same issue downloading something else then it is not a Firefox issue2013-01-28T21:20:48-08:00feer56https://support.mozilla.org/en-US/questions/948739#answer-402803<p>If you are are experiencing the same issue downloading something else then it is not a Firefox issue. Also, please have a look at the following as copied from another contributor.
</p><p>A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
</p><p>Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

<hr>
<p>Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools &amp;gt; Add-ons &amp;gt; Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools &amp;gt; Add-ons &amp;gt; Appearance).
</p><pre> Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
